Didn't get any time to work on this over the weekend sadly. I'll update you when I do.

thanks. If I can help on anything? I got one for my wiffy and one for my daughter and got earache for breaking one as they are fighting over this.

vicinc, have you tried

I have a simalar issue with my PE. I think I killed the filesystems with a random act of dd and getting my if and of mixed up. I can't connect to my PE with adb, but I can use the u-boot terminal (Thanks nikkie for the pics!). Here is an excerpt from the log that I think describes the problem. Not able to mount root. I think I shot the partition table.

Quote:

[ 15.578948] 0801 503280 sda1
[ 15.582779] No filesystem could mount root, tried: ext3 ext2 vfat msdos ntfs fuseblk
[ 15.590658] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
[ 15.598956] Rebooting in 1 seconds..

Does anyone have an idea about how to manually start adb services from the u-boot menu? Is it even possible?
The other route I was thinking about was to connect the usb to a Linux box and run tftpboot from the u-boot and have a script fdisk the PE and rewrite the partition tables. Would this help vicinc too? Does anyone have the details of the partition tables so I can give it a try tonight after work?

Many thanks,
Jim :-)

vicinc · 10-25-2011, 12:49 PM

if you find a way to start adb in uboot is great, but the commands are not docummented in uboot.
i have adb (android boots fine on me but without any of the eink drivers loading) but still can not do much about it. any ideas?

Yeah, I've seen your post Jim. I'm not sure how to fix the problem for either you or Vicinc. It is not possible to start ADB from u-boot, it needs the android os to actually be running.

As it turns out, the various flash drives are not partitioned - fdisk doesn't know what the crap to do with them. However, you probably can share a kernel with tftp and boot that kernel from u-boot. That might work. The other route is to use busybox from u-boot to dd a new image onto that drive from your flash drive. I'm not really willing to start dd'ing things to my partitions though, since I don't want to end up in the same place as you two. ;-) I can, however, send you the dd images from my ubi filesystems. I'll try and do that tonight.

perldude69 · 10-25-2011, 03:40 PM

Nikkie, the dd images will be great. I have the ones I created before I destroyed everything, but the only one that is readable is #5.
I am installing Linux now in hopes that I can do something over tftp. You mentioned busybox over u-boot. Do you know how this is started?

Thanks,

Jim

What do you mean by "readable"? The images are ubi file systems, so unless you have something which can mount them, you're not going to be able to do anything with them. They should be dd'd to ubi0_0, ubi0_1, etc.

busybox is a command in uboot, unless I'm remembering wrong. If so, you'll have to tftpboot a kernel to get access to busybox.

The link to the ubis is here. The .tar.gz file is 312MB, so do us both a favor and don't download until you know you want to use them.

System is ubi0_0.img. This may be of use. Maybe.

busybox does not work on serial uboot.

Have to use tftpboot then, I guess...

perldude69 · 10-26-2011, 05:05 PM

Have you ever found exactly what you need on the Internet only to discover that some joker has placed everything behind some site signup system that is broke?
I found a site that has a fully functional uboot image for the Arm9 processor. They also have tutorials on their site on how to use uboot to restore partitions.... You just need to be able to download their files..... Behind some password protected forum that is broke. .. Argg!
OK rant over. I think if I can get to this stuff, I may make some progress.

On the bright side, I got tftp to work, and I can transfer files to the PE. It is almost midnight again, and I don't think I can make it tomorrow on four hours of sleep again. :-( Maybe on the week end?
On a side note, I used the latest Ubuntu to set up the tftp server. What happened? The GUI sucks raw eggs. It is like they want to loose users... I am tempted to give Red Hat another run....

Good luck all.

nikkie · 10-26-2011, 07:36 PM

Yeah, I just discovered the same thing. I went all ranty about it. I switched to Gnome, but Gnome3 has it's own issues. Redhat has the same problem since they are using Gnome3 also. Irritating as all hell.

Could you post instructions on doing the tftpboot under Ubuntu? I'd appreciate it. Why are you looking for u-boot images anyway? Isn't your u-boot working?

vicinc · 10-26-2011, 08:53 PM

what files are you looking, i will try a search for you as well.
the cpu is ARMv5TE
http://www.gobolinux.org/packages/armv5te-softfp/

do not know if any of this is helpful to you.
